Confuse Your Customer, Then Explain Simply: They Buy It

An article in the Journal of Consumer Research examines the effectiveness of a new confusion-based sales technique called "disrupt-then-reframe." The researchers found that by presenting a confusing sales pitch to consumers and then restating the pitch in a more familiar way, they were able to increase sales of a candy bar in a supermarket, increase students' willingness to pay to join a student...

Corals Added To IUCN Red List Of Threatened Species For First Time

For the first time in history, the IUCN Red List of Threatened Species includes ocean corals in its annual report of wildlife going extinct. A comprehensive study of marine life sponsored by Conservation International concluded that three species of corals unique to the Galapagos Islands could soon disappear forever. The 2007 IUCN Red List designates two of the corals as Critically Endangered,...

Improved Manufacturing Process: Software Cuts The 'Chatter' In High Speed Machining

An engineer has helped find a way to "cut the chatter" in high-speed machining of aluminum and titanium aircraft parts. Chatter in milling is an instability that arises because the cutting tool vibrates, making oscillating patterns on the work piece. The tool goes over the patterns, making the tool vibrate even more, yielding deeper patterns in the work piece, worsening until eventually the...

Manic Phase Of Bipolar Disorder Benefits From Breast Cancer Medication

The manic phase of bipolar disorder favors destructive behaviors. Stemming it quickly is important. Tamoxifen's effects were dramatic -- 63 percent of patients responded vs. 13 percent on placebo -- and it kicked in faster than many current medications. Tamoxifen skips some of current drugs' biochemical steps and acts directly on the enzyme protein-kinase C, giving scientists a more direct target...

Mars: Mysterious Ridges At The Mouth Of Tiu Valles

Mars Express shows the mouth of the Tiu Valles channel system on Mars. The mouth of Tiu Valles is an estuary-like landform. On Earth, an estuary is the tidal mouth of a river valley, or the end that meets the sea and fresh water comes into contact with seawater. In such an area, tidal effects are evident.

Mathematics Might Save You A Trip To The ER

In an effort to better understand seasonality, or cyclic recurrences of disease, researchers have developed mathematical models utilizing daily data to more accurately predict the timing, severity and impact of disease. Developing such precise models is a step toward improving disease surveillance and public health alert systems, both of which are crucial to preventing the spread of some diseases.

More Sick Leave Given To Men By Male GPs Compared With Female Counterparts

Male patients are given more certified sick leave by male doctors compared with the amount of sick notes given to females by female doctors, a new study has revealed. Mild mental disorders (MMDs) such as depression and anxiety were the commonest cause of complaint by women, followed by musculoskeletal problems for which males sought a higher proportion of medical attention. The research revealed...

New Emissions Testing Regulation Gives Repair Shops Reasons To Cheat

In the never-ending quest to make sure cars are not spewing large quantities of pollution into the air, states are implementing new and easier ways to ensure automobiles are both safe and environmentally friendly. But there's a potential problem with the new plan, according to a business professor: repair shops have very strong incentives to cheat, but not in a way that helps reduce pollution.

New Technique Can Be Breakthrough For Early Cancer Diagnosis

Early detection of disease is often critical to how successful treatment can be. Therefore, the development of new methods of diagnosis is a hot research field, where every small step is of great importance. The technique is more sensitive and more reliable than other available techniques in molecular diagnostics.

Possible Vaccine Target For Chlamydia Identified

Scientists have identified a potential target for the development of a vaccine against Chlamydia trachomatis, the most prevalent sexually transmitted bacterial infection in the world. An estimated 2.8 million Americans are infected with Chlamydia each year, according to the CDC. Many are not aware that they are infected.

Putting Stem Cell Research On The Fast Track

Engineers have developed tools to help solve two of the main problems slowing the progress of stem cell research -- how to quickly test stem cell response to different drugs or genes, and how to create a large supply of healthy, viable stem cells to study from only a few available cells.

Taxol Bristle Ball: New Delivery Method For Anti-Cancer Drug

Chemists have discovered a way to load dozens of molecules of the anti-cancer drug Taxol onto tiny gold spheres. The result is a ball many times smaller than a living cell that literally bristles with the drug. Researchers hope to use the Taxol bristle ball to deliver large quantities of Taxol directly to cancer cells.

Unique Role For Blood Formation Gene Identified

All blood cell production in adults depends on the steady work of a vital gene that if lost results in early bone marrow failure cancer geneticists have found. Their research reveals an unexpected role for the gene in sustaining the adult blood-forming system, and opens novel strategies for targeting the gene, which is often involved in a type of childhood leukemia.

Global Survey Reveals Significant Gap In Meeting World's Mental Health Care Needs

Mental disorders rank among the top 10 illnesses causing disability, according to the Global Burden of Disease and Risk Factors published in 2006. Yet, the world's mental health care needs are largely going unmet, especially in less developed nations but also in high-income countries, according to results from a new survey of 17 countries conducted as part of the World Health Organization's World...

Hardy Rice: Less Water, More Food

Scientists have produced a new type of rice that grows better and uses water more efficiently than other rice crops. Rice is a water guzzler when compared to other crops. It typically uses up to three times more water than other food crops such as maize or wheat and consumes around 30 percent of the fresh water used for crops worldwide. In conditions where water is scarce, it is important to have...

Mutations In The Insulin Gene Can Cause Neonatal Diabetes

Insulin gene mutations can cause permanent neonatal diabetes, a rare form of diabetes that affects very young children. This is the first time that an insulin mutation has been connected to severe early onset diabetes. The researchers describe 10 mutations. These alter the way insulin folds. Misfolded insulin may interfere with cellular processes in ways that kill cells that produce insulin. The...

Drug-free Treatments Offer Hope For Older People In Pain

Mind-body therapies, which focus on the interactions between the mind, body and behavior, and the ways in which emotional, mental, social and behavioral factors can affect health, may be of particular benefit to elderly chronic pain sufferers. A new study provides a structured review of eight mind-body interventions for older people, including progressive muscle relaxation, meditation, hypnosis,...

New Lung Cancer Guidelines Oppose Certain Vitamins, Suggest Acupuncture

New evidenced-based guidelines from the American College of Chest Physicians provides 260 of the most comprehensive recommendations related to lung cancer prevention, screening, diagnosis, staging and medical and surgical treatments. The guidelines cite there is little evidence to show lung cancer screening impacts mortality in patients, including those who are considered at high risk for the...


Mold Linked To Asthma

A new study has found that removing indoor mold improves the symptoms of people with asthma. Asthma UK figures show the prevalence of asthma in Wales is among the highest in the world, with 260,000 people receiving treatment for their asthma with the rate of hospital admissions for adults 12 percent more than anywhere else in the UK.

Mouse Model For Schizophrenia Has Genetic On-off Switch

The researchers developed the transgenic mouse by inserting the gene for mutant Disrupted-In-Schizophrenia-1 (DISC-1) into a normal mouse, along with a promoter that enables the gene to be switched on or off. Mutant DISC-1 was previously identified in a Scottish family with a strong history of schizophrenia and related mental disorders.
